\section{Existing Systems}

For inspiration we have looked at some existing systems. There exist different kinds booking systems. For instance, seat reservations in trains which we have seen at \cite{DSB}, or for flight booking \cite{Momondo}. However, we have decided to focus on \cite{Kino} since it is most related to our project. We will take a closer look at how their system works and what their layout looks like.

In \figref{fig:biosystem} we have an image of what kino.dk's system looks like. They give you the option to choose between three ticket types with a dropdown of how many you would like to order. By the look of the seats on the image representation of the hall, they are using a dynamic system which gives them the option to change the size of a hall, since they have different sizes.
